To me personally Retroarch sucks since it takes GB's of storage and is so confusing I think I would have a stroke, so probably nobody here knows how to get it on there, since you can't really emulate the N64 at all.

ii saw smth online about a virtual pack on the wii u that you can play some n64 titles

oh thanks, i saw some nintendont stuff and virtual console. now i can play games lol
